Hi, glad to see you using ECharts for development! I think the code shown in the screenshot you provided is almost right. If you want to call a function handler and pass some variables to it, you could add some extra properties for the `span` tag, for example, `data-name=”${params.name}”`, and then in the handler function, the param `name` can be fetched by `target.getAttribute('data-name')` or `target.dataset.name`. Note that the handler function should be accessible globally, for instance, to mount it to `window` or your own any other global context.
Sample code is available on ECharts Gallery: https://gallery.echartsjs.com/editor.html?c=xir8UiRFq9&v=2 Thanks, Zhongxiang. On 2020/07/17 09:32:57, "908260461" <t...@qq.com> wrote: > 你好,我想问下 echart-饼图 -tootip-formatter点击事件,要在点击事件里面做一些操作, 请问应该怎么写呢>
